I found a gizmo at the dump that had a small propane cylinder (about 1/2
the volume of a 14 oz cylinder). Propane, I think - it has propane
cylinder threads and the gizmo had a flame detector at the end of the
pipe. And it had a tap on it that pierces the cylinder, but does not
have a built-in valve.

The cylinder's sealing disk can be replaced, but I wouldn't think that
this "schedule" cylinder would be reusable.

I never seen this size cylinder, nor one that needed to be pierced.
Anybody know what they're used for? And why the piercing (the only
thing that I've thought of is the elimination of the check valve that
normal cylinders have)?

Looks to me like a CO2 cylinder or an a compressed air cylinder for an air
gun. Just my best guess!!!

I'm gonna guess and say it's part of a halide torch (to detect
refrigerant leaks)

The piercing part is the thing that makes me doubt my first guess.
That, and the color of the tank.

Hmm. Red.

Isn't that Plutonium Tri-Arsenide?

Definitely not CO2 - its vapor pressure is around 800 psi and this tank
is propane-ish strong (propane's vapor pressure 120 psi +-).

I thought that was uranium hexaflouride ???

Oh yeah, speaking of halogens, a few weeks ago I found the strangest thing
on the street corner (seriously, just laying there) - a half-full tank of
chlorofluoromethane (R22/23? I forget). Any ideas whatsoever to use this
stuff for besides refrigeration? If nothing else, how much is it worth?
(And in ten years? g)

I just had 1.5 pounds of R22 added to my home central air system
yesterday, for 20 bucks a pound for the freon.

Just refrigeration, but they used R-22 in other stuff besides HVAC,
like air dryers for your compressor. R-22 is not nearly as expensive
as R-12, but a full 30-pounder is still probably $70 - $100 so it's
worth something.

The only part that might cause concern about "finding a bottle just
sitting there on the street corner" is that you don't know where it's
been... And without a gas chromatograph and other fancy lab tools,
you may never know. (But if you have access to one, you can make sure
it's 'the good stuff' or know to turn it over to the authorities.)

You can get an idea if it is what it's supposed to be by checking
cylinder pressure and consulting the temperature/pressure charts, and
then warming or cooling the cylinder and check it again. If the
pressures match the R-22 chart, it's probably R-22 inside - but you
can't check for contaminants.

That would be a wonderful way for an unscrupulous contractor to get
rid of a bottle of contaminated refrigerant from a compressor
burn-out, or 'mixed contaminated' refrigerant that happens when some
idiot tries putting R-22 or R-134a into an R-502 system, other than
paying a WHOLE LOT (I'm guessing $500 minimum, probably more) to have
it disposed of properly - take your recovery machine and pump it out
into an empty disposable cylinder, and dispose of it (illegally) by
leaving it on the curb at 2 AM.

(Oh, and if you plan to do this you make sure you wipe your
fingerprints off the bottle, and remove the cardboard over-carton that
might have the shipping label with the supply house address on it.
They could trace it back.)

Call me paranoid if you like, but I sure wouldn't want to add some
to my system as a top-off, and find out I just contaminated ANOTHER 5
pounds of refrigerant (that will have to be pumped out and disposed
of) with the crap from the mystery bottle. Or worse, I just dosed a
good compressor with a big slug of burn-out acids...

Just be careful. Most of this stuff generates poisonous gas when burnt.
e.g. - don't use it as a shield gas or a source of fuel.....

I understand a small amount can knock out installers that did torch or match test
for leaks.

At 20 bucks a pound, I assure you, I won't be trying that.
